8. Julianne Moore
Best: Boogie Nights (1997) The idea of porn as art is a difficult sell for most, but if anyone was going to do it, it was Paul Thomas Anderson, whose sprawling (on all fours) epic is arguably still his most enjoyable film to watch. Moore plays the eloquently phrased mother figure, who manages somehow to transcend the stinking tragedy of the rest of the film's motley crew of characters, and disarmingly steals almost every scene she's in. Worst: Nine Months (1995) Marketed almost entirely on the lie that it was sort of a follow up to Four Weddings And A Funeral, this travesty of a comedy conspired to replace the potential of its great cast with mountains of sap.
